» TP-Link TL-WN722N on Ubuntu 10.04: "compat-wireless-2.6.38.2-2.tar"

'via Blog this'

Note: according this guy this set of steps also works for Fedora 15.

I had a lot of trouble getting this card to work. Here is how I finally got it.

I am running 2.6.32-30-generic-pae #59-Ubuntu SMP
running "lsusb" shows the following line for my device: 0cf3:9271 Atheros Communications, Inc.

I tried a bunch of different compat-wireless versions and this one finally did it. At the time, it was the latest stable release. The daily snapshots were causing kernel panics ... Download it, decompress it and build it:


$ tar xvf compat-wireless-2.6.38.2-2.tar.bz2
$ cd compat-wireless-2.6.38.2-2
$ ./scripts/driver-select ath9k_htc
$ sudo make
$ sudo make install

I had to download version 1.2 of htc_9271.fw the firmware from here and copied the file to /lib/firmware.

I was getting wlan%d instead of something reasonable like wlan0. Running sudo ifconfig wlan%d showed me the mac address which I could use to add an entry to /etc/udev/rules.d/70-persistent-net.rules. Heres the entry I added: (note that the browser adds newlines here, but you should add just two lines: one for the comment, and one for the rule)


# USB device 0x0cf3:0x9271 (usb)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="54:e6:fc:94:91:35", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="wlan*", NAME="wlan2"

reload the drivers by running:

sudo modprobe ath9k_htc

Now plug in the device. There were a lot of other steps that I followed while trying to get this to work, so I may have left something out.
